xref: /wasmtime-44.0.1/scripts/publish.rs (revision 9fc41bae)
1 //! Helper script to publish the wasmtime and cranelift suites of crates
2 //!
3 //! See documentation in `docs/contributing-release-process.md` for more
4 //! information, but in a nutshell:
5 //!
6 //! * `./publish bump` - bump crate versions in-tree
7 //! * `./publish verify` - verify crates can be published to crates.io
8 //! * `./publish publish` - actually publish crates to crates.io
